Don't know what to say, other than that Tom Osborne is on record himself as crediting the switch to defensive speed as the difference maker that led to the national championships.
That defensive speed was obtained by following what the Florida schools were doing at the time. That is what Kevin Steele's influence brought.
I suppose I can infer that you believe that NU under Osborne didn't recruit speed on defense before the '90s?
Dude, you don't need to "infer" anything. I'm telling you that TOM OSBORNE HIMSELF says he started recruiting for defensive speed after 1990, having watched those speedy Florida (and Georgia Tech) teams thwart his offense.
That would seem to suggest that however much speed Tom Osborne had recruited before 1990, he realized he had to step up his game in the new college football landscape that put a premium on DEFENSIVE SPEED.
Or to look at it another way, in keeping with the thread, Nebraska needed to target and secure better talent to become the '93-'97 juggernaut we remember.
I suppose I can infer that Tom Osborne's doesn't know what Tom Osborne was thinking as well as you do?
